Application filed July 5, 1917. Serial No. 178,687. v

To LZZ w/wm t may conce/rn.'

Be it known that I, VILLIAM C. ZincnN- rUs, a citizen of the UnitedStates, residing at Kingston, in the county of Luzerne and State ofPennsylvania, have invented a new and useful Drumhead, of which thefollowing is a specification.

The device forming the subject matter of this application is adapted toconstitute a aart of a drum can ail or other container l a a a and oneobject of the invention is to provide a simple and inexpensive butabsolutely reliable means whereby a cover can be locked in position on acontainer.

` Another object of the invention is to provide means whereby access maybe had to the edge of the cover, to permit the cover to 'be pried out.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains With the above and other objects in view which willappear as the description proneeds, the invention resides in thecombinai tion and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment ofthe invention herein disclosed canbe made within the scope of what is claimed, without departing from thespirit of the invention.

In the accompanying drawings Figure 1 shows the invention in top plan;

Fig. 2 is a section taken approximately on the line 2-2 of Fig. 1;

Fig. 3 is a section taken approximately on the line 3 3 of Fig. l;

Fig. e is a perspective view showing a drum or container whereunto thedevice forming theJ subject matter of this application has been applied.

In the accompanying drawings, the numeral 1 indicates a can, ordinarilymade of metal. Assembled as indicated at 2, in any suitable manner, withthe end of the can 1 is a top 3 which preferably is made of metal, thetop 3 being depressed or spaced from the end of the can 1, as will beclearly understood from Fig. 2. The top 3 is prolonged in a directionapproximately parallel to the axis of the can 1 to form an annularshoulder 4f, which is extended in a direction approximately at rightangles to the axis of the can 1 to form an annular flange the inner edgeof the flange 5 being extended in a direction approximately parallel tothe axis of the can l to form an annular lip 6.

The numeral 7 denotes a cover, ordinarily made of metal and including anangularly disposed rim 8 which fits closely within the lip 6. The outeredge of the rim 8 is fashioned into a bead 9 which rests on the flange5. It is to be` observed that the rim 8, engaging the lip 6, spaces thebead 9 from the shoulder Ll, as vindicated at 10, so that a screw driveror other suitable tool may be inserted between the bead 9 and theshoulder' 1, to permit the cover 7 to be 4pried loose. v c

Any desired number of pivot elements 11 are mounted, incircumferentially spaced c relation, in the top 3. Buttons 12 aremounted intermediate their ends on the pivot elements 11, to swingthereon. The buttons 12 overhang the bead 9 and hold the cover 7 inplace, the buttons being yheld down closely on the top 3, so that theycan be turned only when a considerable force is applied to the button.The buttons 12 are provided along their longitudinal edges withprojecting flanges 14. The flanges serve to reinforce the buttons and toprevent them from bending. Further, a tool of any kind may be insertedbetween the flanges 14, to facilitate the rotation of the buttons 12 onthe pivot elements 11. When thebuttons 12 are rotated on the pivoteleients 11, as aforesaid, to clear the bead 9 of the cover 7, the covermay be pried loose, as described, by meansof a screw driver or othertool inserted into the spacey 10. The bead 9 is disposed flush with theouter sur face of the top 3, so that the buttons 12 may engage over thebeads, as shown in Fig. 2. The outer ends of the buttons 12 bear with astrong frictional hold on the upstanding rim 2O of the top, as indicatedat 21, and consequently an accidental turning of the buttons is notlikely to take place.

Having thus described ,theinvention, what is claimed is 1 n In a deviceof the` class described, a re ceptacle; a top having an invertedU-shaped bead receiving the end of the receptacle, the top beingprolonged parallel to the axis of the receptacle to form a shoulder, theshoulder being extended at right angles to the axis of the receptacle to`define a an e having an annular inwardly extended 11p disposed parallelto the axis of the receptaaie; a. cover provided With a riin fittingclosely in the lip, the rim having ay bead engaged with the flange andspaced from the shoulder, the outer surface of the bead lbeing flushwith the outer surface of the top; and a button pivoted intermediate itsends on the top, one end of the button overhanging the bead, the otherend of the bntton being fri'ctionaliy engaged with the Llp-shaped bead,the U-shaped bead bearing throughout its entire Width against the 1eceptaole to withstand the thrust of the button, the button havingreinforcing side Hangers facilitating the turning of the button andincreasing the hold of said other end of the lbutton on the U-shapedbead.

In testimonyv that I claim the foregoing as my own I have hereto aiXedmy signature.

WILLIAM CHARLES ZIEGENFUS.
